my quick thoughts:
- make sure you are using MS4W 2.2.9 (latest)
- make sure your shp has a qix file with it (created by shptree.exe)
- test draw speed with shp2img.exe command with -map_debug 5
- make sure no projections-on-the-fly are occurring
....start with that anyway...

I’m running the latest version of MS4W on a virtual private server with
the following:
- 2003 Server
- IIS 6.0
- Intel Xeon CPU 3.20Ghz
- 640MB RAM
I have one shapefile 850KB and a basic mapfile like below:

END #end of layer
END # end of mapfile
I’m sending WMS GetMap requests to the layer from my localhost and
monitoring CPU on the server.
Every time I send a request the server CPU hits 100% until the request ends.
1) Is 640MB RAM enough to cope with this simple request?
2) Is there anything wrong with the mapfile?
3) Are there any methods I can use to tune this further?
Cheers,
Steve
